mm: add VM_BUG_ON_PAGE() to page_mapcount() Add VM_BUG_ON_PAGE() for slab pages. _mapcount is an union with slab struct in struct page, so we must avoid accessing _mapcount if this page is a slab page. Also remove the unneeded bracket. Signed-off-by: Yalin Wang <yalin.wang@sonymobile.com> Acked-by: Kirill A.
